       from zero

SYNOPSIS
       #include <math.h>

       long int lround(double x);
       long int lroundf(float x);
       long int lroundl(long double x);

       long long int llround(double x);
       long long int llroundf(float x);
       long long int llroundl(long double x);

DESCRIPTION
       These functions round their argument to the nearest  integer  value,  rounding  away  from
       zero,  regardless  of  the current rounding direction.  If x is infinite or NaN, or if the
       rounded value is outside the range of the return type, the numeric result is  unspecified.
       A domain error may occur if the magnitude of x is too large.

RETURN VALUE
       The rounded integer value.

ERRORS
       EDOM   The magnitude of x is too large and (math_errhandling & MATH_ERRNO) is non-zero.

CONFORMING TO
       C99.
